Answer 2

Given: The size of a class is 8 and its upper limit (not included) is 18.  

To find: The lower class limit.

Solution: The lower class limit is 10.

The size of a class is the range of units for which the frequency is given in grouped data. According to the question, the upper limit is not included in the size of the class. Now, the formula to calculate the size of a class can be written as shown below.

$size = upper - lower$

Thus, the values given in the question are substituted in the terms given in the formula. Then, they are rearranged to find the value of the lower limit.

$8 = 18 - lower$

$lower = 10$

Therefore, the lower class limit is 10.
